Cullum’s subsidiary (EMS Industries Limited) manufacture ram pumps for the wastewater and the biogas industries, specialising in performance, quality and durability.
This is achieved through EMS’s uniquely designed ram pumps, where each pump is customised for the individual job to ensure maximum efficiency
EMS’s pumps are tough wearing and require less maintenance through their life cycle. They have demonstrably saved their customers money and reduced their energy usage.
Applications:
- Utilities (Wastewater / Slurry)
- Energy from Waste
- Mining
- Any application where water with high solid contents requires processing

Ram Pumps
The VRM pump series is engineered to handle objects up to 75mm in size, making it an ideal choice for heavy-duty de-sludging applications, 24-hour operation, and quiet functions. With a maximum pressure capacity of 8 bar and an impressive pumping rate of up to 480 litres per minute, our Vertical Ram Pumps provide reliable and efficient water solutions. Find out more at: www.innovativepumpingsolutions.com/vrm-range/ Our VRM’s are versatile, capable of creating a suction vacuum of 0.85 bar, equivalent to 8.5 meters static suction. Explore our VRM range and experience the power of gravity-driven technology today.
Currently we have the CVR (Compact Vertical Ram Pumps) and the CVRG, both come with a 200mm ram. The CVR is the smallest of all our ram pumps and one of the most popular for projects where high pressures aren’t needed. The CVRG has a few differences which enable it to process more abrasive materials, such as grit and small stones, they are primarily used for transferring sludge to and from primary settlement tanks and de-sludging. They have a maximum flow rate of up to 140 litres per minute and can reach up to 4 bar. The Compact Vertical Ram Pumps are an ideal choice for: - Suction of sludge up to 10% dry solids - Flow rate of 140 litres per minute - Energy efficiency and monitoring - Slow speed operation Find out more at: www.innovativepumpingsolutions.com/cvr-range
Our CVRD (Compact Vertical Ram Duplex) range offers all the power of a CVR and more, with two rams that can give twice the flow at a more consistent rate. One ram pump pulls in as the other is pushing out, giving a more time efficient flow. The CVRD200 has a flow rate of 300 litres per minute and can reach up to 4 bar. We currently have the CVRD200 and the CVRD300. The CVRD300 is able to process food waste as well as the general grit, sludge and rags and can pump up to 900 litres per minute and reach up to 5 bar.

Our Vertical Ram Hydraulic Pumps (VRH) range which enables a larger pressure than the VRM’s. They can reach up to 25 bar, the VRH’s can also carry a greater volume and flow of 1800 litres per minute. All of our VRH’s can create a suction vacuum of 0.85 bar the equivalent to 8.5 meters static suction. Find out more at: www.innovativepumpingsolutions.com/vrh-range/
